PIPE.

Specification of Letters Patent.

Patented May 1, H9117,

Application filed November 17, 1915. Serial No. 62,047.

1 t) Hu 1 0122 it may concern.

Be it known that 1, JOHN B. Monnow, a subject of the King of GreatBritain, residing at Bay Shore, in the county of Suffolk and State ofNew York, have invented certain new and useful Improvements in Pipes;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to new and useful improvements in smoking pipesand one of its objects is the provision of a device of this character,which shall be simple, durable and eflicient, and which may bemanufactured and sold at a comparatively low cost.

A further object of this invention is the provision of means forsupporting a perforated diaphragm in spaced relation to the inner end ofa stem of a pipe to prevent saliva and nicotin from entering the mouthof the user from the bowl or shank of a pipe.

A still further object of this invention of the above stated characteris the provision of an enlarged space formed in the shank of a pipe, andhaving the rear walls beveled upwardly and outwardly to prevent theaccumulation of saliva and nicotin from returning to the bowl andsaturating the tobacco therein.

Further objects of this invention will appear as the specificdescription is read in connection with the accompanying drawing, inwhich Figure l is a sectional side elevation, illustrating theapplication of the perforated diaphragm to the end of the stem of a pipeconstructed in accordance with my invention.

Fig. 2 is a fragmentary sectional view on an enlarged scale, and

Fig. 3 is a perspective view of the perforated diaphragm, illustratingthe attaching arm secured thereto.

Referring to the drawings the numeral 1 designates the bowl of a pipeconstructed of any desired shape and having an enlarged opening 2 in theshank 3 of the pipe to receive a stem 4 having a reduced portionthereon. The reduced portion of the stem 4 is provided with its innerend beveled as at 5 in the direction of the bore 6 of the stem i toprevent the accumulation of saliva or nicotin from entering the mouth ofthe user.

The rear wall of the enlarged portion 2 is beveled upwardly andoutwardly as indicated at 7 to prevent the saliva and nicotin fromentering the bore 8 and passing into the bowl 1 and soaking the tobaccotherein.

A diaphragm 9 constructed of metal or hard rubber is provided with aplurality of apertures therein and the center aperture 11 is of largerdimensions than the remaining apertures 10 for the purpose of allowingthe passage of a pipe cleaner therethrough, when the diaphragm has beenpositioned within the enlarged opening 2 of the shank 3 of the pipewhich will be hereinafter more fully described.

A. plurality of arms 12 adapted to be passed through the perforateddiaphragm 9 and clenched thereto as illustrated at 13. The arms 12 arebent downwardly to a point intermediate their length and outwardlytherefrom forming parallel attaching arms 14. The parallel attachingarms 14 are driven into the inner end of the stem 4 and can be moldedtherein if desired, to a point intermediate their length and are adaptedto support the diaphragm 7 intermediate the ends of the bore 8 of theshank 3 and the ends of the stem 4 and in engagement with the side wallsof the enlarged o1i enings 2, which will preveent nicotin and tobaccosoaked saliva from passing into the bore 6 of the stem 4. i

From the foregoing description it will be seen that this invention willmake any pipe to which it is applied a mild and cool smoking pipe as theperforated diaphragm acts for the purposes of delaying and cooling thesmoke.

Having thus described my invention, what I claim is A pipe comprising abowl, a shank extending rearwardly from the bowl, said shank having achamber opening out through its rear end and a reduced bore eX- tendingfrom the end wall of said chamber to the bowl, a stem having one of itsends in said chamber in spaced relation to said end wall and having itsbore in alinement with said first bore, a diaphragm located in thechamber between said end wall and stem, said diaphragmhaving a pluralityof 011- cularly arranged openings and a central opening, the centralopening being in alinephragm in engagement with the Wall of said 10 mentwith said bores, a plurality of arms eX- chamber.

tending through the diaphragm and bent In testimony whereof I affix mysignature around the periphery thereof, said arms in presence of twoWitnesses.

havin inclined portions extendin from said p eriphery in the directionof t he axis JOHN of said diaphragm and being bent to eX- Witnesses:tend in parallel relation to each other and HAROLD E. BARNES, driveninto the stem to support the dia- CONSTANTY SELWA.
